Patents Assigned to ADVANCED CHITOSAN SOLUTIONS BIOTECH
  • Patent number: 11718828
    Abstract: The present invention concerns a method for obtaining an implantable cartilage gel for tissue repair of hyaline cartilage, comprising particles of chitosan hydrogel and cells that are capable of forming hyaline cartilage, said method comprising a step for amplification of primary cells in a three-dimensional structure comprising particles of physical hydrogel of chitosan or a chitosan derivative, then a step for re-differentiation and induction of the synthesis of extracellular matrix by said amplified cells, in the same three-dimensional structure, wherein said cells are primary articular chondrocytes and/or mesenchymal stem cells differentiated into chondrocytes. The present invention also concerns the cartilage gel obtained thereby, and its various uses for cartilage repair following a traumatic lesion or an osteoarticular disease such as osteoarthritis.
